If your computer is slow, or crashes frequently, you may suspect a virus. But how can you be sure? Accurate diagnosis can be tricky, so let's run through major symptoms, minor clues, and a few surefire ways to tell.
Your system suddenly runs much slower, and the key here is suddenly. If it progressively slows down, it's probably getting bogged down by too many programs running in the background, you haven't defragmented it recently or ever , or you are nearing full capacity on the hard drive. Note that new toolbars and shortcuts often come bundled with software you actually want; they may not be malicious — just annoying. If you hit the start button in the lower left corner of your Windows screen and depending on the Version of Windows you have either find the run command or just type CMD in the search box, a black box should pop-up.
This is a prompt used by computer technicians to run programs at a deep level within the computer and it's often used by the pros to remove viruses. As a result, some malware meaning viruses, spyware, and other nasty stuff will disable the feature to make it harder for the user or a tech to remove the virus. In a similar fashion, many viruses will prevent the computer from accessing the Windows Update feature, which can also assist in virus removal. So if you go to control panel, Security, and click Windows Update, and your computer can't launch that feature, it's another clear sign you have a virus.
I think this is a bad idea. Virus writers are sneaky and will often name virus files to look like parts of the Windows operating system or other common programs. Conversely, many legitimate parts of Windows have weird names that sound like viruses to a layman. I have heard horror stories of people thinking they were deleting a virus only to realize after a reboot that they had disabled a mandatory component of the operating system.
Then they had a dead computer that needed a complete Windows reinstallation. But one place where you can get useful info in the task manager is the networking tab. This tip alone is not a good enough metric for virus diagnosis, but it's a clue as you compile information about the state of your computer.
There are lots of free virus scanners online that can tell you if you have some form of malware on your computer. Personally, I like to run two or three programs, because there are hundreds of thousands of viruses, all with different heuristics behavior patterns , so you increase your chances of diagnosis if you use multiple programs with multiple and varied virus definitions.
One tip: when you scan for viruses, be sure to turn off or disable any other security software. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question Report abuse. Details required :.
